Introduction to Oscillators

Oscillators are electronic circuits which generate a continuous output at an adjustable frequency. Common applications for oscillators include clock signals, audio signal processing, and filtering. Oscillators can be categorized into analog and digital types. Analog oscillators utilize operational amplifiers (op amps) or active components to generate their output. Digital oscillators consist of digital logic gates and/or digital logic controllers to generate a periodic signal.

SIT1602BI-12-30E-66.666660E Application Field and Working Principle

The SIT1602BI-12-30E-66.666660E is a stability-enhancing digital oscillator with excellent performance. It is suitable for use in clocks, sensors, and high precision applications. It features high reliability and long-term stability. It has a maximum frequency of 66.66 MHz and is accurate to an SNR of ±1ppm.

The oscillator consists of a main oscillator and a reference oscillator. The main oscillator consists of a voltage-controlled oscillator (VCO), a clock-adjustable digital filter, and an output stage. The output of the main oscillator is used to generate a periodic signal. The reference oscillator is a low-power, high precision oscillator that provides a reference frequency for the main oscillator. The reference oscillator ensures that the main oscillator frequency is in line with the desired frequency by providing a constant frequency.

The VCO converts an applied voltage into an oscillation frequency. The output stage generates a stable output signal from the oscillator frequency. The digital filter eliminates the low-order noise of the output signal. The output stage maintains an accurate frequency over temperature and supply voltage fluctuations.

The SIT1602BI-12-30E-66.666660E is a practical solution for high frequency clock applications. It can also be used in devices that require high frequency, such as radio receivers, digital signal processing (DSP) applications, etc. With its low phase noise and high-performance features, it is an ideal device for advanced clock and control systems.
